  • Objectives : This study was performed to investigate the discriminative criteria of 6 kinds of Achyranthis Radix by HPLC/DAD. Methods : 20-hydroxyecdysone is isolated by silica gel column chromatography ($CHCl_3$:MeOH, 7:1-1:1 v/v) and identified by nuclear magnetic resonance, A high-performance liquid chromatographic method with diode array detection was used to identify 20-hydroxyecdysone in A. japonica. The analysis was performed using $C_{18}$ column with isocratic elution consisted of 18% acetonitrile and 82% water and the detection was carried out by DAD at 254 nm. 6 kinds of Achyranthis Radix from different locations were extracted in MeOH. Each extracts was analyzed by HPLC in same condition as used in analysis of 20-hydroxyecdysone. The identities of each extracts were determined by comparing the retention time and UV spectrum with that of reference compound. Results : 1. A. japonica and A. bidentata showed the similar patterns of HPLC chromatogram and 20-hydroxycedysone was present in both of them because the peaks having the same retention time and UV spectrum as 20-hydroxyecdysone were shown in the HPLC chromatograms of A. japonica and A. bidentata 2. Cyathula officinalis and C. capitata showed the similar patterns of HPLC chromatogram. The peak having the same retention time and UV spectrum as 20-hydroxyecdysone was shown in the HPLC chromatogram of C. capitata but not shown in the HPLC chromatogram of C. officinalis. 3. Two species of medicinal drugs from Sacheon province showed similar patterns of HPLC chromatogram. Achyranthis Radix from Sacheon(wild) did not have 20-hydroxycedysone but Achyranthis Radix from Sacheon(cultivated) showed the peak having the same retention time as 20-hydroxyecdysone but UV spectrum of the peak was different from that of 20-hydroxyecdysone. Conclusions : These results suggested that 20-hydroxyecdysone could be the discriminative criteria for Achyranthis Radix contain 20-hydroxyecdysone though they belong to different genus and species. And the patterns of HPLC chromatogram also could be the discriminative criteria as the different species of Achyranthis Radix belonging to the same genus showed similar patterns of HPLC chromatogram.

  • Objectives : The present study was undertaken to determine whether the water extract of Achyranthis Radix, which is the roots of Achyranthes japonica (Achyranthis Radix, AR), is efficacious against collagen-induced arthritis (CIA) in DBA/1J mice. Methods : Mice were immunized with bovine type II collagen and orally treated with AR-W (50 and 100 mg/kg/bw) from days 21 to 42 after immunization. Arthritis was evaluated by arthritic score, histological examination of knee joint and serological markers such as TNF-${\alpha}$, $PGE_2$ and anti-type II collagen (C II)IgG. Results : The results showed that comparing with untreated CIA mice, treated with AR-W significantly suppressed the clinical score and joint tissue pathological damages, reduced the serum levels of TNF-${\alpha}$, $PGE_2$ and anti-C II IgG in CIA-mice. These results suggest that AR-W can effectively alleviate inflammatory response on CIA, and anti-inflammatoy of AR-W can be attributed, at least partially, to the inhibition of inflamamtory mediators, $PGE_2$ and TNF-${\alpha}$, in CIA. Conclusions : This study suggests that AR-W has a therapeutic potential in inflammatory joint diseases such as rheumatoid arthritis.

  • According to herbalogical bibligraphy and literature, therapeutic effects of Achyranthis Radix on arthritis was as follows, 1. Achyranthis Radix of Amaranthaceae is divided into five species-Achyranthes japonica, A. bidentata, A. longifolia, A. fauriei, Cyathula capitata, C. officialis and the characteristic, taste, channel entry, effects and main treatments were alike. 2. Winefrying stood for repairing treatement method for Achyranthis Radix Before repairing treatment method, Achyranthis Radix had three tastes(bitter, sour, and sweet) and calm and not poisoning characteristic. After repairing treatment method, the bitter taste was disappeared, and calm and not poisoning characteristic was changed into warm characteristic. 3. Effects of Achyranthis Radix were quicking the blood and dispelling stasis, liver-kidney supplement and strengthening musculo-skeletal system. Main treatments were relief of lumbar and knee joint pain, static menstrural block and wind-cold- damp impediment. 4. Contraindication of Achyranthis Radix was sympthom caused by spleen-kidney yang vacuity, upper burner disease and lower burner hemorrhage etc. Being used in pregnant woman, it could incur abortion. 5. Contraindication of Achyranthis Radix was beef, milk and mutton. It's fear was Radix Cynanchi Stauntonii and Semen Plantaginis. It's aversion was the firefly. Herba Taraxaci, Carapax Amydae, Carapax Testudinis and Radix Cynanchi Stauntonii. From above results, I suppose Achyranthis Radix has enough herbalogical foundation and could be used to treat arthritis and it is necessary to make a profound study of it.

  • Objectives : Peripheral nerve injuries are commonly encountered clinical problem and often result in severe functional deficits. The aim of this study is to evaluate the effects of aqueous extract of Achyranthes japonica(AJ) on functional recovery in sciatic nerve after crushed sciatic nerve injury. Methods : In the present study, the animals in the AJ-treated groups received the aqueous extract of AJ at the respective doses orally for 13 consecutive days. In order to assess the effects of the aqueous extract of AJ on function recovery in crushed sciatic nerve injury, sciatic functional index(SFI) was performed. c-Fos expression in the paraventricular nucleus(PVN) and ventrolateral periaqueductal gray(vIPAG), and neurofilament, and the expressions of brain-derived neurotrophic factor(BDNF), nerve growth factor(NGF) following crushed sciatic nerve injury in rats were investigated. For this, immunohistochemistry and western blot were performed. Results : In the present study, crushed sciatic nerve injury showed characteristic gait changes showing decrease of SFI value and treatment with the aqueous extract of AJ significantly enhanced the SFI value. Neurofilament expression in the sciatic nerve was decreased by crushed sciatic nerve injury and treatment with the AJ increased neurofilament expression. The expressions of BDNF and NGF in the sciatic nerve were increased following crushed sciatic nerve injury and treatment with the AJ significantly controlled the sciatic nerve injury-induced increment of BDNF and NGF expressions. c-Fos expressions in the PVN and vIPAG were increased following crushed sciatic nerve injury and treatment with the AJ significantly suppressed the sciatic nerve injury-induced increment of c-Fos expressions. Conclusions : These results suggest that AJ treatment after crushed sciatic nerve injury is effective in the functional recovery by enhancing axonal regeneration and suppressing of pain.

  • Objectives : This work was designed to investigate the effect of The root of Achyranthes japonica Nakai (AJN) water extract on serum deprivation reperfusion-induced apoptosis in PC-12 cells and transient middle cerebral artery occlusion (tMCAO)-induced ischemic brains of rats. Methods : Apoptosis in PC12 cells was induced by serum deprivation and reperfusion. The cells were treated with AJN water extract at doses of 0.5 and 1.0 mg/ml for 24 hr after inducing the apoptosis. Cell viability was determined by WST-1 assay. The expression of caspase-3 protein was determined by Western blot. Ischemic brains were prepared from tMCAO-induced ischemic rats after oral administration with AJN at dose of 50 and 100 mg/kg, and then brain infarction was measured by TTC staining. Results : AJN significantly increased the cell viability in apoptocic-induced PC-12 cells, and also decreased the expression of caspase-3 protein. Furthermore, the administration of AJN significantly inhibited tMCAO-induced brain infarction in rats. Conclusions : Our results suggest that AJN extract has a neuroprotective property via suppressing the apoptosis in PC12 cells and the infarction of ischemic brains.
